How to Fix ArialMT Missing Font Error in PDF Files
Question details
The user needs to understand why a PDF created from a Word document reports 'ArialMT' as a missing or unembedded font, despite the document only using Calibri and Times New Roman.
- Product
- Device & OS
- not provided
- Scenario
- Running a preflight report or checking font properties in a PDF reader after converting a Word document to PDF.
- Observed behavior
- The PDF properties or preflight report lists ArialMT as present but not embedded, which triggers a missing font warning during inspection or printing.
Ensure you have access to a PDF reader or editor capable of viewing document properties, and keep your original Word document handy in case you need to re-export the file.
Inspect PDF Font Properties and Metadata
Determine exactly where ArialMT is being referenced in the PDF to see if it belongs to actual text content, embedded metadata, or hidden elements.
During the conversion process from Word to PDF, default system fonts like ArialMT can be accidentally assigned to hidden elements, paragraph marks, bullet points, headers, or metadata. Checking the font properties will reveal if the font is actually necessary for the document's visual layout.
Launch your PDF in a professional PDF reader or editor and navigate to 'File' > 'Properties' (or Document Properties).
Select the 'Fonts' tab in the properties window. Look for 'ArialMT' in the list of fonts used in the document.
Check if ArialMT is listed as 'Embedded Subset' or missing. If it is missing, note any substitution fonts being applied.
If you have access to a preflight tool, run a font report to locate exactly which page or object contains ArialMT. Often, it is tied to an empty space or a default bullet point created during the Word-to-PDF export.
Force Font Embedding When Exporting from Word
Prevent missing font errors by ensuring all standard and custom fonts are fully embedded when saving or exporting the original Word document to PDF.

Frequently Asked Questions
Why does a standard font like ArialMT show as missing in my PDF?
Standard fonts can show as missing if the system viewing the PDF lacks the specific font variant (like ArialMT instead of standard Arial), or if the PDF creation software referenced the font in the document's hidden metadata but chose not to embed its subset to save file size.
Will a missing ArialMT font affect how my document looks?
It depends on where the font is used. If ArialMT is applied to visible text content, the PDF reader will substitute it with another font, which might alter text alignment and layout. If it is only attached to metadata, empty paragraph marks, or blank spaces, it will not affect the visual appearance.
How do I completely remove an unused font from a PDF?
To completely strip an unused font, you can use the preflight feature in advanced PDF editors to remove unused objects and hidden text. Alternatively, it is often easier to go back to the original Word document, clear all formatting from empty spaces, and re-export it to PDF.
